Any security features that are used on regular continuous forms
can be used on continuous mailers. The security of the content of the mailer
is a concern that does not affect other continuous forms. The different types
of gluing available will provide different levels of security to the enclosed
content, see Types
of Gluing. To protect data from being viewed by anyone other than the
recipient, blockouts are used on the mailer in different locations to prevent
data from being readable. For more information on other security features that
are available, see Security
Features.
